Generalized mathematical models in design optimization [PDF]
The theory of optimality conditions of extremal problems can be extended to problems continuously deformed by an input vector. The connection between the sensitivity, well-posedness, stability and approximation of optimization problems is steadily ...

Mathematical Optimalization of Data Channels
Hadmérnök, 2019 The cognitive radio channel allocation is envisioned to solve the challenge of electromagnetic spectrum scarcity focusing on radio frequency’s data networking in the ever-changing radio environment. Dynamic electromagnetic spectrum management is crucial to avoid decreasing the bit rate and allocate the appropriate channel power in cognitive radio ...

Advanced Engineering Materials, EarlyView.This study examines the mechanical properties of triply periodic minimal surfaces (TPMS)‐based lattices, analyzing 36 architectures in elastic and plastic regimes. It evaluates the applicability of beam‐based scaling laws to TPMS lattices. Rigidity arises from the alignment of members with the load direction and solid regions preventing rotation.

Advanced Engineering Materials, EarlyView.This study presents rapid evaluation methods for scan strategies in powder bed fusion (PBF) of polymers with a NIR laser as an example for its application. It uses line buffer‐based calculations and point density fields to predict the performance of four different scan strategies. The methods show promising results in laser‐based PBF of polymer samples,

The Infinite Principle: The Mathematics of Optimism
This paper introduces the infinite principle: a mathematical framework proving that optimism is the rational choice when comparing bounded and unbounded outcomes. Rooted in expected value theory, the principle demonstrates that any option with unbounded upside mathematically dominates alternatives with bounded outcomes, provided the downside is finite ...

Validation of a model of regulation in the tryptophan operon against multiple experiment data using global optimisation [PDF]
, 2009 This paper is concerned with validating a mathematical model of regulation in the tryptophan operon using global optimization. Although a number of models for this biochemical network are proposed, in many cases only qualitative agreement between the ...
